The double rotating wheels with opposite directions are arranged in the throwing cavity 11, so that stirring of washing water in the throwing cavity 11 is increased, dissolution of a detergent is promoted, and washing and cleaning effects are improved; the first rotating wheel 21 drives the second rotating wheel 22 to rotate, namely the first rotating wheel 21 is a driving wheel, and the second rotating wheel 22 is a driven wheel, so that the rotation synchronism of the first rotating wheel 21 and the second rotating wheel 22 is kept, the motion interference and collision between the first rotating wheel 21 and the second rotating wheel are avoided, and the rotation stability is improved; and the first rotating wheel 21 drives the second rotating wheel 22 to rotate, and only the driving moment is transmitted to the first rotating wheel 21, so that simultaneous driving of the two rotating wheels is avoided, and the driving structure is simple.
In this embodiment, for driving the first rotating wheel 21 to rotate, the water flow injected into the delivery cavity 11 by the water inlet structure 30 pushes the first rotating wheel 21 to rotate. The first rotating wheel 21 is driven to rotate by setting the water flow injected into the throwing cavity 11, and the first rotating wheel 21 drives the second rotating wheel 22 to rotate together when rotating; the first runner 21 and the second runner 22 are simultaneously pushed to rotate relative to the water flow injected into the delivery cavity 11, and the water flow only pushes the first runner 21, so that the pushing force on the first runner 21 is improved.
In other embodiments, a drive motor may be provided to drive the first wheel 21 in rotation.
In this embodiment, referring to fig. 1, the detergent box 100 further has a water box 40, the detergent box 10 is drawably located in the water box 40, the water box 40 has a water box body 41 and a water box cover 42, and the water inlet structure 30 is disposed on the water box cover 42. Detergents include laundry powders, laundry detergents, softeners and the like.
Referring to fig. 5 and 6, the structural arrangement of the first runner 21 and the second runner 22 and the positional relationship with the water intake structure in the present embodiment are described.

The water inlet structure 30 is positioned above the rotary dissolving structure 20, one or more water inlets 31 are formed in the water inlet structure 30, and the first rotating wheel 21 is positioned above the second rotating wheel 22 in an inclined manner; by arranging the water inlet structure 30 above the rotary dissolution structure 20, the water flow flowing through the water inlet 31 is favorably accelerated continuously under the action of self gravity after being sprayed, and the pushing force of the water flow is favorably increased; and after the water flow falls onto the first blade 211, gravity of the water flow also gives the first blade 211 a downward force, which is beneficial to increasing the rotation speed; and facilitates defining the water jet range, positioning the first and second rotors 21 and 22, and simplifying design considerations.
For the arrangement of the mounting positions of the first runner 21 and the second runner 22 in the dosing chamber 11, consideration needs to be given to ensuring agitation of the wash water; in the water inlet process, especially for a siphon water inlet type throwing cavity, the liquid level of the washing water in the throwing cavity 11 is higher, and in order to increase stirring of the washing water in the throwing cavity 11 and promote dissolution of the detergent, the first rotating wheel 21 and the second rotating wheel 22 are arranged as close as possible to the bottom wall of the throwing cavity 11, but the first rotating wheel 21 and the second rotating wheel 22 are positioned in the washing water; in the water inlet process, after the first rotating wheel 21 is positioned in the washing water, when the water flow flowing through the water inlet 31 impacts the first rotating wheel 21 positioned in the washing water, most of impact force is buffered by the washing water, so that the rotating speed of the first rotating wheel 21 is slower; therefore, the first rotating wheel 21 is arranged above the second rotating wheel 22 obliquely, so that the impact force of water flow is transmitted to the first rotating wheel 21, the second rotating wheel 22 is closer to the bottom surface of the throwing cavity 11, the first rotating wheel is far away from the bottom surface of the throwing cavity 11, so that the water flow flowing through the water inlet 31 impacts the first rotating wheel 21 instead of the washing water, the water flow has larger driving force and is transmitted to the first rotating wheel 21, the first rotating wheel 21 rotates and drives the second rotating wheel 22, and the second rotating wheel 22 agitates the washing water in the throwing cavity 11, so that the detergent is promoted to be dissolved.
The overflow port 114 is arranged on the cavity wall of the putting cavity 11, the liquid level in the putting cavity 11 is definitely lower than the lower end face of the overflow port 114, the horizontal plane where the axis of the first rotating wheel 21 is arranged is located above the lower end face of the overflow port 114, namely, the axis of the first rotating wheel 21 is located above the horizontal plane c where the lower end face of the overflow port 114 is located, the upper half part of the first rotating wheel 21 is ensured not to be definitely located above the liquid level of washing water, so that water flowing through the water inlet 31 can directly impact on the first blade 211 located at the upper half part, the larger impact force of the water flow to the first blade 211 is ensured, the first rotating wheel 21 is pushed to rotate, and the second rotating wheel is further driven to rotate. In order to ensure the stirring force of the second rotating wheel 22 on the washing water in the throwing cavity 11, the horizontal plane where the axis of the second rotating wheel 22 is located below the lower end face of the overflow port 114, so that the lower part of the second rotating wheel 22 is located below the liquid level of the washing water, and the stirring of the washing water is realized. The lower end surface c of the overflow port 114 is positioned between the horizontal plane where the axis of the first rotating wheel 21 is positioned and the horizontal plane where the axis of the second rotating wheel 22 is positioned; a siphon structure is arranged in the throwing cavity 11, and the plane of the upper end of the siphon column is lower than the lower end face of the overflow port 114.
The axes of the first runner 21 and the second runner 22 are arranged in parallel, and the water flow flowing through the water inlet 31 is sprayed to the area between the axes of the first runner 21 and the second runner 22, so that the sprayed water flow flows out from between the axes of the first runner 21 and the second runner 22, so that the water flow gives impact force to the first runner 21 and simultaneously the gravity of the water flow also gives downward force to the first blade 211 and the second blade 221, thereby being beneficial to increasing the rotation speed and promoting dissolution of the detergent. The first rotating wheel 21 is arranged above the second rotating wheel 22 in an inclined manner, so that the occupied space of the first rotating wheel 21 and the second rotating wheel 22 in the up-down direction is reduced, water flow falls to the second blades 221 after impacting the first blades 211, the second blades 221 are pushed to a certain extent, the water flow rotates along with the second impellers 221 and is pushed, and the dissolution of the detergent is promoted.
The axis of the first rotating wheel 21 is horizontally arranged in the left-right direction, the axis of the second rotating wheel 22 is horizontally arranged in the left-right direction, and the axes of the first rotating wheel 21 and the second rotating wheel 22 are both horizontally arranged, so that the horizontal movement of the washing water in the throwing cavity 11 is facilitated, the impact to the corners in the throwing cavity 11 is facilitated, and the residue of the washing agent is avoided. The angle α between the plane a in which the axes of the first runner 21 and the second runner 22 are disposed and the horizontal plane b is 40 ° to 50 °, and preferably the angle α between the plane in which the axes of the first runner 21 and the second runner 22 are disposed and the horizontal plane is 45 °.
In order to increase the structural strength of the first runner 21 and the second runner 22, an arc-shaped first connecting rib 212 is arranged between two adjacent first blades 211, and the structural strength between the two adjacent first blades 211 is increased by arranging the first connecting rib 212. An arc-shaped second connection rib 222 is provided between two adjacent second blades 221, increasing the structural strength between the two adjacent second blades 221.
The first blades 211 are axially arranged and extend radially outwards, and the radial dimensions of the two axial ends of the first blades 211 are smaller than the radial dimensions of the middle part; that is, the capability of the middle part of the first blade 211 to wave the water flow is larger than that of the two ends, and the radial extension sizes of the two ends of the first blade 211 are smaller, that is, the capability of the two ends of the first blade 211 to push the water flow is not large, so that the capability of the middle part of the first blade 211 to push the water flow is guaranteed, the pushing of the water flow in the detergent input area is guaranteed, and the dissolution of the detergent is improved. The second vane 221 is axially disposed and extends radially outwardly, and the radial dimension of the second vane 221 at both axial ends is smaller than the radial dimension of the middle portion.
In order to realize the pushing of the first runner 21 to the second runner 22, the sum of the outer diameter D of the first blade 211 and the outer diameter D of the second blade 221 is set to be greater than or equal to the distance between the axis of the first runner 21 and the axis of the second runner 22, the outer diameter D of the first blade 211 is the maximum distance between the outer end of the first blade 211 and the axis of the first runner 21, and the outer diameter D of the second blade 221 is the maximum distance between the outer end of the second blade 221 and the axis of the second runner 22; that is, the first blade 211 and the second blade 221 may be spatially contacted such that the first blade 211 pushes the second blade 221 to rotate, transferring the rotational torque to the second runner 22; and the first rotating wheel 21 and the second rotating wheel 22 are close to each other, so that the structure is compact, and occupied space is reduced.
For the arrangement of the first blade 211, the first blade 211 may be provided with a first blade body 2111 and a deformable portion 2112 located at an end of the first blade body, the deformable portion 2112 being located at an end of the first blade 211 away from the axis, the deformable portion 2112 being provided with an elastic material; it is advantageous to increase the contact area between the first blade 211 and the second blade 221 by deformation of the deformable portion 2112 when the first blade 211 pushes the second blade 221, and to transmit the pushing force to the second blade 221; and the deformable portion 2112 stores elastic energy by deformation, and when the deformable portion is reset, part of the elastic energy is applied to the second blade 221, so that the rotation speed of the second rotating wheel 22 is increased, and the dissolution effect of the detergent is improved; and damage when the first blade 211 collides with the second blade 221 is avoided. The sum of the outer diameter of the first blade body 2111 and the outer diameter of the second blade 221 is greater than or equal to the distance between the axis of the first runner 21 and the axis of the second runner 22, ensuring the urging force of the first blade 211 and the second blade 221.
Referring to fig. 3, 4 and 13, the arrangement of the water intake structure in this embodiment will be described.
The axes of the first rotating wheel 21 and the second rotating wheel 22 are horizontally arranged, and the axially extending water jet needs to be arranged and is sprayed on the first rotating wheel 21 and the second rotating wheel 22; the first implementation mode of the water inlet is that the water inlet is in a long strip shape which is parallel to the axis of the first rotating wheel 21, and water flow ejected from the water inlet forms a continuous strip shape which diffuses outwards and is ejected onto the first rotating wheel 21 and the second rotating wheel 22; the second implementation of the water inlet is to provide a plurality of water inlets 31, and the plurality of water inlets 31 are arranged in a direction parallel to the axis of the first rotary wheel 21, and the water flow ejected from the water inlets 31 spreads outward in a downward direction with a plurality of ejected water flows ejected onto the first rotary wheel 21 and the second rotary wheel 22 in the axial direction.
In this embodiment, in a second implementation manner, the water inlet structure 30 is provided with a plurality of water inlets 31, and the water flowing through the water inlets 31 is sprayed to the area between the axis of the first runner 21 and the axis of the second runner 22. For convenience of description, the first runner 21 is defined as being rotated in the forward direction, and the second runner 22 is defined as being rotated in the reverse direction. The water flow is sprayed to one side of the first rotating wheel 21 close to the second rotating shaft 22, so that the first rotating wheel 21 is given forward rotating driving force, and if the water flow is sprayed to one side of the first rotating wheel 21 far from the second rotating shaft 22, the first rotating wheel 21 is given reverse rotating driving force; it is thus necessary to secure the injection range of the water flow through the water inlet 31, and set the area between the axis of the first runner 21 and the axis of the second runner 22.
